I'd check the fuel pressure regulator. It has a fuel line in and fuel line out and a vacuum hose. With the truck running and a fuel pressure gauge on, pull the vacuum line off the regulator. Pressure should increase 8-12lbs. Put the vacuum hose back on, pressure should return to normal. If not, replace the regulator. Also, if gas squirts out of the regulator when you pull the vacuum hose off, the regulator's bad.
